This is really, really disappointing. I've been pretty critical of Dark Sky at times for being mediocre for more than maybe 12 hours out, but for very short term forecasts it worked great. I spent a fair amount of time outdoors and getting a 30 minute heads-up for "drizzle" versus "heavy rain" was excellent and really let me time how long to stay outside for.
I'd really, really like a replacement on Android. While Wunderground could be it, it's unfortunately not. The app is heavy and crappy and ad-laden and weirdly non-nonsensical.
